If the phenolphthalein solution turns pink, that means that the plastic bag is permeable to ammonium hydroxide. If it remains colorless, then the plastic bag is not permeable to ammonium hydroxide. If the contents of the plastic bag turn pink, then the plastic bag is permeable to phenolphthalein. If everything remains colorless, then the bag is impermeable to both ammonium hydroxide and phenolphthalein.
One example would be the smell of food when it is tightly sealed in a plastic bag; the smell is effusing out of the small holes in the plastic bag.
